Contribution of excitatory amino acid receptors of the retrotrapezoid nucleus to the sympathetic chemoreflex in rats
(WILEY-BLACKWELL, 2011)
In the present study, we evaluated the role of glutamatergic mechanisms in the retrotrapezoid nucleus (RTN) in changes of splanchnic sympathetic nerve discharge (sSND) and phrenic nerve discharge (PND) elicited by central ...
Respiratory syncytial virus (RSV) pneumonia in a southern muriqui (Brachyteles arachnoides)
(WILEY-BLACKWELLHOBOKEN, 2012)
Background An adult male Brachyteles arachanoides, kept in captivity since 1990, was found dead without apparent clinical evidence. Methods Necropsy report, histopathology, immunohistochemistry, and ultrastructural examination ...
Diffuse-regressive alterations and apoptosis of myocytes: Possible causes of myocardial dysfunction in HIV-related cardiomyopathy
(ELSEVIER IRELAND LTD, 2009)
Objective: To determine the frequency of cardiac alterations in necropsies of AIDS patients in pre-HAART era and better understand the pathogenesis of HIV-related cardiomyopathy. Design: Retrospective study of 94 complete ...
Effects of six carbohydrate sources on dog diet digestibility and post-prandial glucose and insulin response
(WILEY-BLACKWELL, 2008)
The effects of six extruded diets with different starch sources (cassava flour, brewer`s rice, corn, sorghum, peas or lentils) on dog total tract apparent digestibility and glycemic and insulinemic response were investigated. ...
Anesthetic Activation of Central Respiratory Chemoreceptor Neurons Involves Inhibition of a THIK-1-Like Background K(+) Current
(SOC NEUROSCIENCE, 2010)
At surgical depths of anesthesia, inhalational anesthetics cause a loss of motor response to painful stimuli (i.e., immobilization) that is characterized by profound inhibition of spinal motor circuits. Yet, although clearly ...
Central mechanisms involved in pilocarpine-induced pressor response
(ELSEVIER SCIENCE BV, 2011)
Pilocarpine (cholinergic muscarinic agonist) injected peripherally may act centrally to produce pressor responses; in the present study, using c-fos immunoreactive expression, we investigated the forebrain and brainstem ...
Ventrolateral medulla mechanisms involved in cardiorespiratory responses to central chemoreceptor activation in rats
(AMER PHYSIOLOGICAL SOC, 2011)
A rise in arterial PCO(2) stimulates breathing and sympathetic activity to the heart and blood vessels. In the present study, we investigated the involvement of the retrotrapezoid nucleus (RTN) and glutamatergic mechanisms ...
